Objective: The Mayo adhesive probability (MAP) score is used to predict the presence of adherent perinephric fat. The study aimed to assess the impact of MAP score on intra- and postoperative outcomes in partial nephrectomy (PN). Materials and Methods: This retrospective analysis encompassed 130 patients treated with either open or laparoscopic PN. MAP scores were calculated, and their relevance to intra- and postoperative characteristics was evaluated. Results: Cases were seperated into 2 groups according to MAP scores [group 1: MAP score <=2 (n=86 (66.15%) and group 2: MAP score >=3 (n=44 (33.85%)]. No significant differences were observed in age, tumor size, body mass index, PN laterality, or radius, exophytic/endophytic, nearness, anterior/posterior location, and preoperative aspects and dimensions used for an anatomical nephrometry scores. Male patients, as well as those with higher American Society of Anesthesiologists scores (>=2) and Charlson comorbidity index (>=4), demonstrated significantly elevated MAP scores (p<0.001, p=0.046, p=0.022). Median operation time was longer [135 (interquartile range (IQR): 120-180) vs 160 (IQR: 140-180) min] in group 2 (p=0.014). Although duration of WIT [28 (IQR: 19.5-37.5) vs 33.5 (IQR: 21.75-41.25) min] and intraoperative bleeding [400 (IQR: 200-700) vs 500 (IQR: 200-900) mL] were higher in group 2, no statistically significant difference was observed (p=0.262, p=0.352). No significant differences were observed regarding intra- and postoperative transfusion requirements or hospital length of stay. Conclusion: Elevated MAP scores are linked to longer operative times, while having a minimal effect on intra- and postoperative complications and outcomes.
